Equation~ 5b + (2b - 4) + (3b -6)= 180.
Answer:
Step-by-step explanation:
If two ratios make a proportion then it can be shown as:
Let's verify the answer choices with this method
A. 1/4 and 5/25
- 1*25 = 4*5
- 25 = 20, incorrect, not a proportion
B. 1/4 and 7/24
- 1*24 = 4*7
- 24 = 28, incorrect, not a proportion
C. 1/4 and 10/48
- 1*48 = 4*10
- 48 = 40, incorrect, not a proportion
D. 1/4 and 9/36
- 1*36 = 4*9
- 36 = 36, correct, this is a proportion
The answer would be x=14 because the 70 degree side would be the same as the (5x) degrees side. So you divide 70 by 5 and that’s how you get 14!!!
Hope this helps!!
The answer is 311/12,the decimal form is 25.916,the mixed number from is 25 11/12
